Replication Flashcards
phosphate
attach to carbon 5, end: phosphate or hydroxel
hydroxl
3 primed end (OH)
phospahte (hydroxl)
5 primed end
anti-parraell
oppossite directions
ribosomes
make proteins/polypeptide
ribosomal RNA (rRNA)
comonent of ribosomes (building block, making up subunits = RNA (ribosomal), intwined with with proteins
messenger RNA (mRNA)
lenar strand, fighting in groove (between large and small), making polypeptides
transger RNA (tRNA)
loopy= not base pair (3 bases), identify, bind, transport a specific amino acid in cytoplasm (to ribosome)
replication
synthesis of anaphase, 4 single stranded to double stranded (2 DNA molecules), happens in nuelcules (where nuclear DNA is)
semi consteravative
each new strand is half old half new, semi conservative
in nucetosomes
bublbles
bubbles
multiple origins ,, untwist molecule, break hydrogen bonds, have 4 DNA polymers, hilacase
what bubble does
hilacase start in middle and go in opposite directions, bubles gets bigger and run into two more bubles,
DNA polymers
can only read parent strand toward 5 prime end, put down complamentary nucleotid along parent strand on both sides, hook them together (nucleotid, on both sides)
template or parent strand
make daughter strand
Leading strand
2 leading strand per bubble, follow hilacase
No breakage, contious, ,
Continuous strand
Lagging behind leading strand,
Hilacase
Unzip or break hydrogen bonds
Untwist
Result of replication
2 identical
Function of mRNA
Get genetic code of DNA in nucleus by transcription and take code to ribosomes
Involved with translation
Translating base sequence to amino acid sequence of a polypeptide
Function of rRNA
Creating peptide bond between amino acids that are in p site and a site
